As a member of Octet, you're automatically entitled to receive an Octet Rewards Visa Card. This is a special Visa debit card account that accumulates funds as you (or the person you nominate) repay your Octet facility. There are no points to redeem or claim. You simply accrue cash as you use your Business Transaction Facility. Your Reward Card is simply a 'thank you' for doing business with your Octet Trading Card.
If you are importing large amounts of stock, you can see how these funds would build up quickly. You are free to spend these funds at any of the 30+ million outlets worldwide that accept Visa.
